The adjustability of this square should be seen as a positive. As others have said, if you have a square that's not adjustable and it gets dropped or damaged, it's junk. With this one, you can re-calibrate the square, if needed.

Woodpeckers says this square is accurate within .008 degrees.

Could you achieve .008 degree accuracy using the method prescribed in the video?

Solving for X yields 0.00167 in. or approximately 0.002 in. at the far end of a 12 in. span. Keep in mind that this number is only for the stated angle accuracy, and does not account for the surface profile tolerance of the blade.

Just laying it out in my CAD program I get .0059" deviation at 48". About a tenth of a sixteenth.

Here's what I came up with:TAN(0.008°) = X / (12 in.)Solving for X yields 0.00167 in. or approximately 0.002 in. at the far end of a 12 in. span.

That is correct. Keep in mind that you double the deviation when you use the flip method shown. 0.002x2=0.004"=0.1mm. I can easily spot 0.1mm if marking knife or something similar is used.@Shane Holland should send us all coupons for popularizing this thread.

I just did a quick crude calculation using the commonly accepted number of approximately .018" of draft (DME mold design) per degree. So at .008º, the offset at the 1 inch level will be .000144" and at the 12" level the offset will be .001728".

That's pretty impressive if it can maintain that level of accuracy. My only concern is the 12" lever arm that can be banged about accidentally.

The calculator returns 0.0067 in. at the end of a 48 in. span. Close enough.

Made me think though: The OneTime Stainless Square is is not the ideal tool for someone looking to setup a track saw or other equipment. It is better suited for layout work, because less pressure will be applied to the blade.

this thread has us thinking a.) TSO will stay with non-adjustable toolsb.) TSO needs to think of another creative way to stir controversy to raise the visibility of our products on forums c.) Shane does a very good job

I'm still trying to decide. What advantage(s) besides being a squaring tool will this have over the Woodpeckers T Square? They both have holes for marking exact dimensions. I'm trying to justify taking this plunge.

I think the utility is as an all-in-one tool. Checking square on inside and outside corners, marking and layout (which the T square would do), blade height or fence offsets on table saws and routers. It has some appeal in that sense, however, you have to wrestle with that price.

I've got news for you. The 1281 style squares get out of square all the time.

Woodpeckers states the following...

"Our Guarantee. We're so confident in the accuracy of the 1281 Square we offer it with a Lifetime Guarantee to stay square to within one-thousandth inch or we'll repair or replace it upon return and inspection by us."

Yep, same guarantee for both 1281 and 1281SS....

- Out of square 1281 => send back to Woodpeckers for re-calibration.

- Out of square 1281SS => re-calibrate it yourself in about 5 minutes or you can always send this one back to Woodpeckers for re-calibration, too.

The larger, easier to see marking holes make the 1281SS worth it to me. I agree with Clark regarding the Incra Rule holes. Way too difficult to find the hole that corresponds to the measurement you want and the holes are prone to breaking pencil lead.

I am with you too, that is the feature I like about these. I am so disappointed with the Incra rules, they are so tender, I take such good care of them and still they kink and are bent. This thing to me seems like a better version of that at least in another form. I've never really been unhappy with Woodpecker.

If I drop any of my many Woodpeckers squares and find they are out of square, they will get a trip back to the company for service.

If always received excellent customer service from Woodpeckers.

+1 on both of these statements.

While in theory it's nice to have adjustability, you still need to have a standard square to adjust the banged up square to and you need to make sure that the standard is accurate to begin with and keep it as a standard only and not use it for anything else, lest the standard becomes out of square.

Easier to just send it back to Woodpeckers...and they do provide fast service.

I did get my set last week and of course, they are lovely - they have a nice heft to them, easy to read, and of course, dead square. I haven't used them on a real project yet so can't comment on how well the notches work for marking in practice.

I'm just questioning whether I really need these; might end up selling as I could use the funds on some other more pressing needs.
